Fig. 5.
Now by pulling b up and pushing it down, we have an elephant like Fig. 5, which will move his tail, trunk, ears, and eyes as naturally as any elephant which has been born and brought up in the circus.
Leaf Photographs.—A very pretty amusement, especially for those who have just completed the study of botany, is the taking of leaf photographs. One very simple process is this: At any druggist's get an ounce of bichromate of potassium. Put this into a pint bottle of water. When the solution becomes saturated—that is, the water has dissolved as much as it will—pour off some of the clear liquid into a shallow dish; on this float a piece of ordinary writing-paper until it is thoroughly wet. Let it become dry in the dark. It should be of a bright yellow. On this put the leaf; under it a piece of black soft cloth and several sheets of newspapers. Put these between two pieces of glass, and with spring clothes-pins fasten them together. Expose to a bright sun, placing the leaf so that the rays will fall upon it as nearly perpendicular as possible. In a few moments it will begin to turn brown; but it requires from half an hour to several hours to produce a perfect print. When it has become dark enough, take it from the frame and put it in clear water, which must be changed every few minutes until the yellow part becomes white.
QUITE IN THE STYLE OF HER MISTRESS.
